Salvia Plant Named &#39;SGRPU03-0&#39;

ABSTRACT

A new and distinct  Salvia  cultivar named ‘SGRPU03-0’ is disclosed, characterized by vigorous plants with a large, upright form and long flowering period. Flowers are dark purple. Calyces are persistent and retain their dark purple color. The new variety is a  Salvia splendens , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Salvia splendens.

Variety denomination: ‘SGRPU03-0’.

BACKGROUND OF THE INVENTION

The new Salvia cultivar is a product of a planned breeding program conducted by the inventor, Michael Uchneat in Bellefonte, Pa. The objective of the breeding program was to produce new Salvia splendens varieties with large, upright plant habits in a range of flower colors and with persistent calyx. The crossing resulting in this new variety was made during May of 2012.

The seed parent variety is an unpatented, proprietary, Salvia splendens referred to as ‘16666-1’. The pollen parent is the unpatented proprietary variety referred to as ‘16651-3’. The new variety was identified as a potentially interesting selection in September 2012, at a greenhouse in Bellefonte, Pa.

Asexual reproduction of the new cultivar ‘SGRPU03-0’ by vegetative cuttings was first performed during October of 2012, at a research greenhouse in Bellefonte, Pa. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘SGRPU03-0’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SGRPU03-0’ These characteristics in combination distinguish ‘SGRPU03-0’ as a new and distinct Salvia cultivar:

1. Vigorous, large, upright plant larger than most Salvia splendens in the trade. 2. Long flowering period from young plant until frost. 3. Calyx are persistent, and color of the calyx is retained. 4. Deep purple calyx and purple corolla.

PARENT COMPARISON

Plants of the new cultivar ‘SGRPU03-0’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘SGRPU03-0’ differ in the following:

1. The new variety begins flower early Spring, the seed parent begins flowering much later. 2. Size of the new variety is considerably larger than the seed parent. 3. Foliage of the seed parent is darker than foliage of the new variety.

Plants of the new cultivar ‘SGRPU03-0’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘SGRPU03-0’ differ in the following:

1. The new variety has deep purple flowers, the pollen parent has red flowers. 2. The new variety produces more branches than the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘SGRPU03-0’ can also be compared to the commercial variety Salvia splendens ‘Saucy Purple’, unpatented. These varieties are similar in most horticultural characteristics; however ‘SGRPU03-0’ differs in the following:

1. The new variety has darker purple flower color than this comparator. 2. A higher percentage of calyx persistence is observed in the new variety. 3. Foliage of the new variety is darker green. 4. The new variety is not sterile, whereas ‘Saucy Purple’ appears to be sterile.

Plants of the new cultivar ‘SGRPU03-0’ can also be compared to the commercial variety Salvia splendens ‘Lighthouse Purple’, unpatented. These varieties are similar in most horticultural characteristics; however ‘SGRPU03-0’ differs in the following:

1. The new variety has a darker purple flower color. 2. Flowering spikes of the new variety are longer than those of ‘Lighthouse Purple’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SGRPU03-0’ grown in a greenhouse, in Santa Paula, Calif., in a commercial 10 inch container.

FIG. 2 illustrates in full color typical flowering spikes of ‘SGRPU03-0’. Age of the plant photographed is approximately 3 months from 3 rooted cuttings. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
